摘　　要：四杆靶靶标是测试光学系统空间分辨率的常用信号源,在红外热成像测试领域有着广泛的用途。采用了MATLAB工程设计计算工具,针对红外热成像计算机性能模拟系统,以视场、目标背景对比度、目标空间频率、成像系统分辨率为自变量,设计了系列四杆靶模拟靶标信号源,为红外热成像计算机性能模拟系统提供了有效的测试图像信号源。The 4 Bars is a kind of useful target in performance testing for optical imaging system, especially for IR imager, In this thesis, By MATLAB tools, a serial of 4 Bars targets are designed for computer simulating system of IR Imaging performance based on the view field, contrast, target spatial frequency and Imager resolve, these simulated targets are very efficient inputs for simulating performance testing.
